Repeated calls of image:copy() cause memory leak

Bugs
1

I tested the other image functions and they don’t have any problems. However image:copy() in the draw function produces a sudden crash; Especially with very large pictures. This is the same problem from: https://codea.io/talk/discussion/521/repeated-calls-to-image-and-sprite-crash-codea

I did call garbagecollect() which fixed the crashing.

@PlatinumFrog it causes a crash because you are creating a new image 60 times a second, and big images require more space and data, which would cause major lagging prior to crashing

You almost certainly don’t want to be calling image:copy 60 times a second
